Alright, so first we'll have to get y on the other side
So
2x+y=-9
-y -y
+9 +9
2x+9=-y
Then divide is all by -1 so y is positive
-2x-9=y
Your answer would be D. The angle C is 47 degrees.
Area of a square is ; 10 * 10 = 100
We have 2 squares so total is 200.
Area of a circle is pi* r^2 = 3.14 * 100 = 314
But we have quarter of a circle so area will be 314/4 = 78.5
Total area of the shape is 200 + 78.5 = 278.5
Answer:
$4.86
Step-by-step explanation:
2.97/11 =.27 .27 x 18= 4.86
<span>Let's say in general you want "n" adjacent squares. Each one needs a top, so that's n toothpicks. Each one needs a bottom, so that's another n toothpicks, and we're up to 2n total. You need one on the far left, and one on the far right, which brings us up to 2n + 2 toothpicks. Now we need to worry about the middle ones. But notice that you don't need n toothpicks for the interior because adjacent squares share. It turns out that you only need n-1. That brings us up to a grand total of 3n + 1 toothpicks, which would be 301 for n = 100.
